The one time I had a failure like yours was going to Big Sky SUNI – coil failed; fortunately the last spare part I packed for the trip was a Ford yellow top coil.

When it cools – it works again. Upon a failure you could bypass the ballast resistor and put a constant 12v to the coil or carry a spare ballast resistor to determine if it is the cause of the problem. It would be best to find the exact cause of the failure.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>I believe Accel has a similar ignition module but I have not tracked how well it works.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>Points and condenser are always your fallback position.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>Ron Fraser<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> Tigers [mailto:tigers-bounces@autox.team.net] <b>On Behalf Of </b>James Burruss via Tigers<br><b>Sent:</b> Monday, October 16, 2017 3:35 PM<br><b>To:</b> tigers@autox.team.net<br><b>Subject:</b> [Tigers] Pertronix Ignition<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial",sans-serif'>On a Saturday drive, my Tiger’s engine shut off instantly as if the ignition key had been turned off. It would not restart. I suspected that the car’s Pertronix II ignition had died, as they have been known to do. Mine had been reliable for several years, although the car is not driven often any more. I had the car taken home on a rollback.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial",sans-serif'>This morning, I began a series of checks. I ruled out the ignition switch as a possible culprit because the starter, gauges and fuel pump all worked. I checked the wiring connections, coil resistance, voltage to the coil, and even fuel in the carburetor; all were fine. So I connected an induction timing light to confirm that there was no spark – except that there was! Then I got in the car and started it. It ran fine.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial",sans-serif'>Which brings me to my question for those who have experience with these ignition systems: Are they known to become intermittent due to heat? Saturday was a warm day, mid-80s, the car had been driven moderately for about 10 miles and its temperature was normal. Needless to say, I no longer trust this system; but I would appreciate knowledgeable comments and/or recommendations for a replacement ignition for a stock 260.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial",sans-serif'>Many thanks!<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:13.0pt;font-family:"Arial",sans-serif'>Jim Burruss <o:p></o:p></span></p></div></body></html>
